Title: Microstructure of Concrete from a Crack-Free Structure Designed to Last a Thousand Years
Author(s): J. Asselanis and P. K. Mehta
Publication: Special Publication
Appears on pages(s): 349-358
Keywords: cracking; high-volume fly ash concrete; mixture design;
petrography; raft foundation
Abstract:A petrographic examination on a companion test slab that was cast and cured under the same conditions as a massive raft foundation was performed to gain insight into the observed crack-free nature of the concrete. The foundation was made of a high-volume fly ash concrete mixture designed to last a thousand years. The absence of cracking is attributed to a homogenous microstructure of the high-volume fly ash system and close attention to the selection of concrete materials, mixture proportioning, and curing.
